Google PCA Manage implementation of cloud architecture Practice Question
A company wants to deploy a containerized application on Google Cloud and needs persistent storage that can be accessed by multiple pods in a GKE cluster concurrently. Which storage solution should they use?
⚠ Common exam trap
Candidates often confuse Persistent Disk's ReadWriteOnce capability with ReadWriteMany, or incorrectly assume that Cloud Storage FUSE provides the same concurrent POSIX access as a true shared filesystem like NFS.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Filestore
Filestore is the correct choice because it provides a managed NFS file server that supports the ReadWriteMany (RWX) access mode, allowing multiple pods in a GKE cluster to concurrently read from and write to the same persistent storage volume. This is essential for workloads like content management systems or shared data processing that require simultaneous access from multiple pods.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Persistent Disk with ReadWriteMany access mode
Why it's wrong here
Persistent Disk only supports ReadWriteOnce; not shared across pods.
- ✗
Cloud Storage via Storage FUSE
Why it's wrong here
Possible but not designed for high-performance concurrent access; more for object storage.
- ✗
Compute Engine persistent disk attached to each node
Why it's wrong here
Attaching to node doesn't provide shared access; each pod on the same node could use hostPath but not multi-node.
- ✓
Filestore
Why this is correct
Filestore provides a managed NFS server that supports concurrent read/write from multiple pods.
